It's perfectly straightforward: you can feed plants on relatively pure chemical nutrients prepared in a factory, and they'll grow. You can also feed plants on impure chemicals such as bone-meal, dried blood, rotted farmyard muck, etc, and they'll also grow. The plants can, of course, neither absorb nor digest the materials mentioned in your last sentence. They have to be broken up by agents in the soil into simple inorganic substances before the plant can make use of them. What, then, is wrong with skipping a stage and putting the required chemicals directly into the soil? So-called organic husbandry is, by my understanding, a set of techniques which aim to increase the levels of the 'agents' you mention. Rather than relying on factories to produce concentrated chemical feeds in an energy intensive fashion the aim is to increase the soils own fertility in the long term in a sustainable way. I hope that to be consistent you plough with a horse and only use wooden implements. -- Martin |
